Abstract

Adhesive articles, particularly useful as reusable closures, comprising a moisture resistant substrate and a removable adhesive covering at least a portion substrate surface, the adhesive having a Moist Loop Test result of at least about 25 N/25mm at a test plate temperature of 5°C. The closure may also include a permanent adhesive covering another portion of the substrate surface. The adhesive articles provide easy application to packages and exhibit good adhesion performance in the presence of moisture, such as from refrigerated or frozen food packaging.
